SURFACE MOUNT WIREWOUND RESISTORS MELF AND GULLWING DESIGNS, 1/2 TO 5 WATT MW SERIES Term.W is RoHS compliant & 260°C compatible RESISTORSCAPACITORSCOILSDELAY LINES Inherent wirewound stability and overload capability Resistance range: 0.005Ω to 50KΩ Excellent T.C. stability (available to ±5ppm/°C) Standard tolerance: ±1% or ±5% (available to 0.01%) Available on exclusive SWIFT TM delivery program! RCD Series MW provide a cost-effective solution for demanding applications. Advantages include superior surge capability, improved temperature stability, moisture resistance, noise, and a significant space and cost savings over molded models. MW3 & MW5 feature compliant gullwing terminals, which act as standoffs to reduce PCB temperature and help minimize TCE stress (utilize compliant terminals in applications with wide temp. gradients). OPTIONS TYPICAL PERFORMANCE CHARACTERISTICS RoHS Option X: Non-inductive Option T: PTC Temp. Sensitive (+80 to +6000ppm/°C) Option P: Increased Pulse Capability Option F: Flameproof (UL94V-0) Option ER: 100 Hour Burn-In Numerous options avail.: special marking, matched sets, Hi-Rel screening, low thermal EMF, etc. Consult factory C .010” [.25] Max MELF B A GULLWING .050 [1.27] typ. .12 [3] RCD Type 1 .10 [2.5] typ.
