Raleigh, N.C. Stackpole Electronics, Inc. has expanded its power metal film ASR and SPR series of axial-leaded anti-surge resistors. The ASR series adds a 1/4-watt body size to the currently available 1 watt, mini 1/2-watt, and mini 1/4-watt sizes.
The SPR series offers 1 watt and mini 1/2-watt sizes and resistance values from 1 Megohms to 12 Megohms. The SPR devices are UL 1676 recognized. In addition, the SPR series has improved the maximum working voltage up to 2000 volts, the maximum overload voltage up to 3000 volts, and the surge withstanding voltage up to 10 KV.
The ASR series is available in resistance values from 100 ohms to 33 Megohms and can withstand surges from 1 KV up to 10 KV depending on size and resistance value.
Both series are suitable for all types of power supply applications. They are designed to meet the harsh pulse requirements found on the input and output stages of switching power supplies. The devices are RoHS compliant.
Pricing: Ranges from $36 to $90 per thousand for minimum quantities.
Availability: Standard delivery is stock to eight weeks.
