Now available from Total Frequency Control Ltd. the type DRH high current filter chokes, with a wide range of inductance and high saturation current. Ideal for use in switching regulated power supply applications, low profile and self-leading, the finished product is varnish coated or insulated with UL shrink-sleeving. The inductors also feature a useful central hole to facilitate automatic mechanical mounting.

This product is ideally suited in applications such as power supplies and power amplifiers, switching regulators, speaker crossover networks and RFI suppression. Power density dictates the dimensions which vary from (3 ~ 5)mm in height and (21 ~ 28)mm in diameter.

Inductance range from 1microH up to 15milliH with maximum current density of 8.0A/mm over an operating temperature of (-20 C ~ 80) C. The product exhibits low DCR values and high saturation currents.
