PFD3215

Document 982F-1 Coupled Chip Inductors – PFD3215 For Flyback, SEPIC and other applications The PFD3215 has a footprint less than 3.2 × 2.3 mm, making this shielded coupled inductor ideal for applications with limited board space. It is designed for use in a variety of circuits including flyback, multi-output buck and SEPIC. These inductors provide high efficiency and excellent current handling in a rugged, low cost part. They can also be used as two single inductors connected in series or parallel, as a wideband transformers or as a common mode choke. + + D L1 VIN C SW L2 C VOUT – – Typical Flyback Converter L2 D + C VOUT – 0.131 max 3,32 0.059 max 1,5 0.078 1,98 0.006 0,15 0.024 0,610 4 AUX 1 L1 2 L2 4 + VIN SW D + L1 C VOUT – 3 Typical Buck Converter with auxiliary output D – + L1 0.088 2,24 VIN + C VOUT C1 Q 0.014 ±0.003 0,356 ±0,0762 1 2 L2 3 0.030 0,762 – 4 0.092 max 2,33 3 1 2 Refer to Application Note, Document 639, “Selecting Coupled Inductors for SEPIC Applications” Typical SEPIC schematic – 0.025 0,635 Recommended Land Pattern 0.028 0,711 Dimensions are in inches mm Core material Ferrite Core and winding loss  Go to online calculator Environmental  RoHS compliant, halogen free Weight  18 – 28 mg Terminations  RoHS compliant silver-palladium-platinum-glass frit.
