Time is flying away, remember the first time we met in Ningbo in the year of 2005. I'm so happy with you and your team. Thanks for your support and let's look forward to the next years together.

—— Mr. Halit vergili

From partner to friend, you always give me surprise for your goods and service. We appreciate it so much. By the way, the pickled fish sauce is so nice. I'm self-confident of my cooking skills again. Don't forgot hot pot date next time.

SQM Radial Type Vertical Cement Ceramic Wirewound Power Resistors

 

Description:

 

The SQM Series are ceramic housed resistors with fiberglass based wirewound or ceramic rod wirewound or metal oxide core.


The materials used and the construction techniques ensure excellent flame resistance, arc resistance and moisture resistance as well as self-extinguishing capabilities. They will withstand the most rigorous loading test.


As resistors in radio and television receivers, hazardous conditions such as smoking and redheat can be completely prevented by the proper choice of power resistors.

 

Test methods:

 

Serial number Project Test conditions Request
1 Appearance Visual observation Clear signs
2 Size The measuring instrument should be used 1/20mm should be consistent with the provisions
3 Resistance value Should use low voltage DC measurements resistance value Should allow scope
4 Li voltage Exchange for 1.42 times the insulation voltage peaks maintain 1min+5S Clear signs
5 Xing may welding

Shafts Win : 235+5 degrees, the water Time : 2S+0.5S, water depth ;3A, 3B-based products for its Chajue 8mm+1mm;1V type products should all water;The remaining products are all from resistance by the main 20-0.5mm

should be consistent with the provisions
6 Raises piece intensity pull test

20N terminals along the axis direction of the pulling force role 5`10 seconds later, by a resistance value of resistance testing

Should allow deviations within
7 Overload Oxide membrane core resistance to the imposition of 2.5 times the rated voltage or by two times the limit voltage components, to a lesser persons. Imposed on the duration 5S; Xianrao core resistance by 10 times rated pressure dissipated loss, the required voltage, or resistance by the main exert every mm long 40V (for smaller), are exerting duration 5S No puncture or fly arc
8 Resistance welding heat Shafts Win : 350+10 degrees, the water Time : 3.5S+0.5S, water depth : 3A, 3B-type products for its Chajia 8mm+1mm;1V type products should all water;The remaining products are all from resistance by the main 20-0.5mm No visible injury marks clear.
9 Vibration Frequency range : 3A, 3B-type products 10Hz~55Hz, -- are all products account for the remaining 10Hz~500KHz 0.75mm, 0.75mm oscillation amplitude to time 6h. No visible injury
10 Rapid temperature changes

Five high cryogenic test cycle, the temperature of 155 degrees, the low temperature -55 degrees, a temperature of the test in each 30min. 1h~2h resume testing after the appearance inspection and resistance value measurements.

No visible injury
11 Room temperature durability Resistance at 15 degrees to 35 degrees with a temperature of between 42 days withstand durability testing, the rated consumption is less than or equal to 15W for the DC voltage on the resistance tests, rated power of more than 15W of resistance device should be used to exchange voltage tests. But the resistance device specifically designed for use in DC, the DC voltage should be used for testing. When resistance makes DC voltage tests, Wenbo voltage should not exceed 5%. The pilot period should 1.5h power, 0.5h power to impose voltage cycle. Voltage value should be amended to rated voltage coefficient multiplied by the square root, or components limit voltage, to a lesser persons. This factor should be amended as follows : The maximum temperature-surface temperature testing (environmental) surface maximum temperature to 70 degrees resistance. Added resistance by the voltage, the value should be calculated +5% scope. In testing to 48h, 500h and 1000h, and in the end 0.5h power outages will be resistance by atmospheric conditions on the resumption of testing standards 1~4h after. Inspection appearance and resistance value. 1000h after insulation resistance measurements. No visible injuries appearance

6, DC load : (applies only to non-Xianrao resistance devices) at the end of the testing, resistance devices should be placed on standards tests atmospheric conditions, the conversion should not exceed 5min, removed from the box after 30min+5min, resistance devices should continue to exert direct current voltage 1min. Rated voltage or components for the voltage limit voltage, choose the lesser, then resistance devices in the standard atmospheric conditions, the restoration of 1h-2h, inspection and measurement of changes in appearance and resistance value insulation resistance.

14 Produce hot and damp A, only one group of six samples, tests without voltage.
B, Group 2 only seven samples, the test should be imposed in the lead-among the elected DC voltage from the series ;0.4V, 6.3V, 10V, 16V, 25V, 40V, 63V and 100V. The voltage devices dissipated by the resistance of 0.01 times the rated consumption to select plant near its low value.
C, Group 3 only seven samples, the test should be installed between the board and arbitrary lead-imposed 20V+2V the DC voltage, the level is raised Duanjie install panels to cathode. Testing time for the entire 504 hours.
DC load (only applicable to non-Xianrao resistance devices), test methods with article 6 of climate sequence test methods. After the test was over, resistance by atmospheric conditions on the resumption of testing standards 1h - 2h, and appearance inspection and measurement of insulation resistance value changes in electric resistance.
