Tsum1pfr-lf Datasheet Link
- Explain how to interpret a datasheet for a hypothetical or niche component using this naming convention.
- Provide a template/guide for engineers who encounter an unknown or legacy part number like this in a Bill of Materials (BOM).
Final advice for procurement: Always request a certificate of conformance and RoHS analysis for any -lf component. Counterfeit or remarked parts may omit lead-free plating, risking assembly defects.
Adjustable Output Configuration:
If the Tsum1pfr-lf is the adjustable version, you need an external resistor divider from VOUT to FB (feedback) to GND. Tsum1pfr-lf Datasheet
- Example: 5V input, 3.3V output, 1A load → PD = (5 – 3.3) × 1 = 1.7W
