Stackpole released the HDM Series of low-cost carbon-film thru-hole resistors that provides moisture withstanding capabilities.
Standard carbon film resistors cannot withstand harsh environmental conditions such as, high temperature, pressure and moisture combined. According to Stackpole, many resistors addressing this issue use metal glaze technology, which is more expensive than carbon film.
The HDM resistor is carbon-film-based and uses a unique material set, processing, and process control to achieve moisture withstanding performance comparable to metal glaze resistors at a fraction of the cost. It will survive at 120°C, two atmospheres of pressure, >98% relative humidity, and rated voltage for 100 hours without failing. The HDM is available in ¼ watt and ½ watt sizes, in tolerances as low as 1%, and in resistance values from 1 ohm to 2.2 Megohms.
Applications include low power industrial controls, security equipment, lighting controls, aviation and aerospace instrumentation, control systems for industrial machinery and manufacturing equipment, marine audio, video equipment and controls.
Pricing: Varies with size, resistance value, and tolerance, and ranges from $0.015 to $0.035 each in full reel quantities.
Availability: In tape and reel and ammo packaging in 5000 piece quantities.
