SMT Power Inductors Military/Aerospace Grade Wire Wound Ruggedized for the Military and Aerospace Industries Height: 0.480” MAX Footprint: 0.75” x 0.875” Maximum Reflow Temperature: 235°C MSL: 1 Electrical Specifications @ 25°C - Operating Temperature -55°C to +125°C Part Number Inductance @0A dc (µH ±10%) Inductance @ Irated (µH TYP) Irated1 (ADC) DCR (mΩ±10%) PL2089 PL2131 PL2141 16.0 41.00 57.8 16.0 40.00 57.8 9.9 6.0 5.0 9.1 23.10 34.5 Notes 1. The rated current as listed is either the saturation current or the heating current depending on which value is lower. 2. The saturation current is the typical current which causes theinductance to drop by 20% at the stated ambient temperatures (25°C and 100°C). This current is determined by placing the component in the specified ambient environment and applying a short duration pulse current (to eliminate self-heating effects) to the component. 3. The heating current is the DC current which causes the part temperature to increase by approximately 40°C. 4. In high volt*time applications, additional heating in the component can occur due PL2085/PL2131/PL2141 Mechanicals 100°C 12 7.3 6.2 11 6.0 5 9.9 6.2 5.1 Core Loss Factor K2 258 413 490 DB (Gauss) = K2 * DI 1.63 * DB2.62 Core Loss (W) = 1.5E-13 * (Freq_kHz) 5. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range. 6. RoHS compliant version (100% pure Sn leads) available.
