Murata transformers have controlled turns ratios

Murata has introduced a series of converter transformers designed for use with Analog Devices' ADM2482/7 transceiver chipsets, which are used to provide isolated RS-485 and RS-422 interfaces.

The 782482 series has controlled turns ratios to ensure consistent performance, while a toroidal construction helps minimise electromagnetic interference (EMI).

Housed in a dual-in-line (DIL) package using UL94 V-0 materials, the low-profile 782482 series has overall dimensions of 9.77mm (0.385in) x 9.14mm (0.360in) x 6.35mm (0.25in).

Nominal input voltages are 3.3V for the 782482/33VC and 5.0V for the 782482/53VC.

Both models have a nominal output voltage of 3.3V and provide 4.0kV DC isolation.

An industrial temperature range of -40 to 85C makes the 782482 series suitable for use in a range of applications.

Both models are RoHS compliant and backward compatible with Sn/Pb soldering systems.

Surface-mount versions of the converter transformers are under development.

Analog Devices' ADM2482/7 are isolated data transceivers with +/-15kV ESD protection and are suitable for high-speed, half-duplex or full-duplex communication on multipoint transmission lines.

The devices employ the Analog Devices iCoupler technology to combine a three-channel isolator, a three-state differential-line driver and a differential-input receiver into a single package.
