    Selection Notes

    • Select by the parameter limits in the table, then confirm the derating curves in the full specification before committing a design.
    • Package and footprint dimensions are listed per part. Verify against your land pattern — the same series can ship in several case sizes.
    • Where the series spans automotive and consumer grades, check the part number suffix. The electrical values may match while the qualification does not.

    Common Questions

    How many part numbers are in the PTG series?

    229. The table above lists every one, sorted by part number.

    What do the parts in the PTG series have in common?

    They share the same ptc thermistor (posistor) construction and case-size family; the differences are the electrical values shown per row.

    Where can I find the full specification for a PTG part?

    Each part number links to Murata's official product page, which carries the detailed specification sheet, reliability data and simulation models.

    Official documentation: PTGL04AR130H2B51A0 on murata.com — detailed specification sheet, reliability test data and S-parameter / SPICE models.
