New Yorker Electronics to stock Vishay IHDM edge-wound inductor series

New Yorker Electronics has announced Vishay Dale’s release of the IHDM Series of edge-wound, through-hole inductors with an 1107 case size.

The Vishay IHDM-1107BBEV-20 and IHDM-1107BBEV-30 inductors are ideal for DC/DC converters, inverters, differential mode chokes, and filters for motor and switching noise suppression in high current, high temperature applications, including industrial, medical, and military systems. The inductors are available with a selection of two core materials for optimized performance depending on the application.

The IHDM Series features a powdered iron alloy core technology with soft saturation current to 422A, providing stable inductance and saturation over a demanding operating temperature range, with low power losses and excellent heat dissipation.  The edge-wound coil provides low DCR down to 0.25mΩ, which minimises losses and improves rated current performance for increased efficiency. Compared to competing ferrite-based solutions, the IHDM-1107BBEV-20 and IHDM-1107BBEV-30 offer 30% higher rated current and 30% higher soft saturation current levels that are stable at continuous operating temperatures to +180°C. The inductors’ soft saturation provides a predictable inductance decrease with increasing current, independent of temperature.

Standard terminals for the IHDM-1107BBEV-20 and IHDM-1107BBEV-30 are stripped and tinned for through-hole mounting. Vishay can customize the devices’ performance — including inductance, DCR, rated current, and voltage rating — through New Yorker Electronics. Customizable mounting options include bare copper, surface-mount, and press fit. To reduce the risk of whisker growth, the inductors feature a hot-dipped tin plating. The devices are RoHS-compliant, halogen-free, and Vishay Green.

Features & benefits:

  • High temperature operation, up to 180°C continuous with no aging
  • Low DCR to minimise losses and reduce temperature rise
  • Powdered iron alloy core technology provides stable inductance and saturation over operating temperature with satisfactory core losses (-55 °C to +180 °C)
  • Soft saturation gives predictable inductance decrease with increasing DC current independent of temperature

Applications:

  • High current and high temperature applications
  • DC/DC converters
  • High current differential mode chokes
  • Inverters

New Yorker Electronics supplies Vishay Dale discrete semiconductors (diodes, MOSFETs and infrared optoelectronics) and passive electronic components (resistors, inductors and capacitors).
