Coilcraft offers their CST Series of high frequency SMT current sensing tranformers that sense current to greater than 10 amps. These transformers are for use between 50 kHz to 1 MHz and feature eight different turns ratios to meet a variety of applications. All Coilcraft current sensing transformers are RoHS compliant and 260°C compatible.
Coilcraft designs and manufactures DC-DC transformers that feature telecom input of 36-72 VDC or 36-57 VAC. DC-DC transformers are also available that feature telecom extended inputs of 14-72 VDC, of VDC input of 2.7-36.
Coilcraft makes many EMI/RFI filters including surface mount and leaded components, LC filters, and signal line filters, which work on RJ-45, RJ-15, and RJ-11 lines. Their LC filters include high and low pass models and feature less than 0.3 dB insertion loss with 50 or 75 Ohm characteristic impedance.
Coilcraft Inc. designs and manufactures low voltage transformers including miniature step-up/flyback types. The company's low voltage transformers are used in harvesting applications and feature only 3.5mm high and 6 mm square. Additionally the transformers feature 100 V winding-to-winding isolation and a coupling coefficient of K > 0.95.
Coilcraft offers the Q3903-AL toroidal transformer that features three 1:1 windings, 500 Vrms winding-to-winding isolation, and optional COTS Plus tin-silver-copper and tin-lead terminations. Furthermore, it has a 210mH inductance minimum and 0.09 ohm DCR maximum, and a temperature range from -40 to +85 degrees Celsius. This part is compatible for use with controllers and evaluation boards from manufacturers like ON Semiconductor and Texas Instruments.
