AI Overview
Square inductor bases or bobbins measuring approximately
are specialized components primarily used for mounting toroidal cores or creating custom, large-current common mode chokes.
Key Features & Types
- Material: Usually made from LCP (Liquid Crystal Polymer) or similar high-temperature, UL 94V-0 rated plastic.
- Construction: Often designed for PCB mounting with 2+2, 4+4, or 5+5 pins (terminal pins).
- Applications: These bases are used for power supplies, line filters, and toroidal common mode chokes.
- Other Options: Some 20mm components are available as finished common mode chokes or inductors.
Components and Alternatives
- 20x20mm Square Inductor Base: Often found at suppliers like Mycoiltech.
- 20 mm Lead Spacing Chokes: Mouser Electronics lists several 20mm lead spacing inductors and chokes from manufacturers like TDK and Bourns.
- Modern Alternatives: For power applications, manufacturers like Panasonic provide smaller (or similar) surface-mount power inductors that offer higher vibration resistance (up to) compared to traditional large base-mounted toroids.
