Enhanced Film Power MELF Resistor ( 3W 150ohm 5%)
EFP301J150RTKZTR2K0
Power Resistor, SMD Resistor
Enhanced Film Power MELF Resistor (EFP), 3W 150ohm 5%, features an SMD-enabled structure with superior anti-surge capability, and offers much better power dissipation than chip resistors. In general usage, a chip resistor operates at around 20% to 30% of its rated power, while a MELF resistor operates at around 50% of its rated power. Therefore, the power density of a MELF resistor is approximately 2 times that of a chip resistor.

Single Surge Performance
Enhanced Film Power MELF Resistor-EFP series,is showing the surge performance from 1uS to 1S.
Surge Power Derating Curve
• Above graph is accurate for NON REPETITIVE applications operating in an ambient temperature of 70°C or less. For temperatures above
70°C, the graph power must be derated further by 1.18% per °C. • For applicable surge power in continuous-surge applications please see SURGE POWER DERATING CURVE above.
