New Vishay Dale Series Delivers High Temperature Operation to 180°C Continuous with No Aging
NORTHVALE, New Jersey, USA – New Yorker Electronics has announced Vishay Dale’s release of the new 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 minimizes 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-percent higher rated current and 30-percent 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 minimize 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).
