PRM1ER-1000-G

PULSE RESISTORS, SURFACE MOUNT RESISTORS CAPACITORS COILS DELAY LINES PRM SERIES OPTIONS RoHS Term.W is RoHS compliant & 260°C compatible High voltage/ high surge capability Cost effective surface mount package Available on RCD’s exclusive SWIFT TM program Option ER: Group A Screening per MIL-R-39008 RCR Option B: Increased power Option X: Non-inductive A ↓ → D Pulse tolerant surface mount resistors! Series PRM withstand high energy pulses, and are superior to conventional film & wirewound types. The heavy duty construction features a ceramic core, enabling improved thermal transfer and long term stability. Elements are protected by flame-retardant molding for excellent environmental performance. Alpha-numeric marking is standard. PRM resistors are cost effective in a wide variety of pulse applications including telecom line feed resistors, snubber circuits, inrush currents, capacitor charge/discharge circuits, lightning surges, etc. ←G→ ↑ F ↓ SUGGESTED PAD LAYOUT C ↑ B ↓ .010” typ PRM1/2,.050” PRM1 ------ ← ↑ ← E → ------ H SPECIFICATIONS RCD Type PRM1/8 PRM1/4 PRM1/2 PRM1 1 Wattage Rating Max.
