TDK · Sensors, Transducers · Disc

B59772C0120A070 from TDK, in a Disc. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1 passive First radial wire lead of the C772 leaded PTC disk (Ød 0.6 mm, lmin 25 mm); the thermistor is non-polarized, Vmax = 260 V AC / Vlink,max = 370 V DC for inrush limiting, or 440 V for overcurrent protection.
2 2 passive Second radial wire lead of the C772 leaded PTC disk (lead spacing 5 mm per drawing); the thermistor is non-polarized, RR = 120 Ω ±25% at Tref = 120 °C.

CAD (KiCad official)

  • Symbol: B59772C0120A070
  • Footprint: Adom_Gen:TDK_B59772
  • 3D model: Disc (KiCad packages3D, STEP)
  • 3D model files: b59772c0120a070-etched.step / b59772c0120a070-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); b59772c0120a070.step / b59772c0120a070.glb are the bare package body.
