Notes
  1. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  2. L min is achieved at maximum extension of the core toward PC board. Complete tuning range is reached within the boundaries of the coil form.

Termination:

  • Pins: Tin-lead over tin over copper over iron
  • Shield can tabs: Tin-silver over nickel over brass

Weight:
7M2 series: 1.00 – 1.06 g; 7M3 series: 1.30 – 1.34 g

Soldering/Washing

Resistance to soldering heat:
Wave solder only. Recommended maximum board surface temperature of 168°C (334°F) for no more than three seconds. Pre-heating is recommended to minimize time over the solder nozzle.
Refer to Soldering Coilcraft Components before soldering.
PCB Washing:
Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
