Open circuit inductance (OCL) test parameters: 100 kHz, 0.25 Vrms, 0.0 Adc, +25 C 4. I : Peak current for approximately 35% maximum rolloff +25 C sat 2. Full load inductance (FLL) test parameters: 100 kHz, 0.25 Vrms, I , +25 C 5. Part number definition: SDCH1Vxxxx-yyyz-R sat 3. I : DC current for an approximate temperature rise of 40 C without core loss. Derating is necessary for AC currents. SDCH1V = Product code rms PCB layout, trace thickness and width, air-flow, and proximity of other heat generating components will affect the xxxx= size code temperature rise. It is recommended that the temperature of the part not exceed +125 C under worst case operating yyy= Inductance value in H, R=decimal point conditions verified in the end application. z= Inductance tolerance -R suffix = RoHS compliant 2 www.eaton.com/electronics
