TE Connectivity's TE Circuit Protection has rolled out a family of nine low rho (low-resistance) surface-mount devices (SMDs) geared for space-constrained mobile applications such as smartphones, MP3/4 players and portable GPS units. According to the company, the devices help provide both over-current and over-temperature protection for the battery pack protection circuit modules (PCMs) used in compact consumer devices.

Manufacturers of handheld consumer products require the smallest possible components that occupy the least amount of board space while helping reduce production costs. Fulfilling these demands, the low rho SMD products provide low-resistance in an industry-standard form factor of 1210 (3 x 2.54 mm), 1206 (3 x 1.52 mm) or 1812 (3 x 4.57 mm) thus meeting board space requirements. In addition, these devices can be assembled with a reflowable soldering technique, as opposed to the spot welding process required by many other components, to save board space and reduce production costs, noted the company.

The low rho SMD device resistance is just 10-25mΩ after reflow process. The devices' low resistance helps reduce power consumption and improve battery efficiency. The nine new devices in the low rho SMD series are all designed for an operating current of 2A and above, added TE Connectivity.

The devices are available for 8 weeks ARO for $0.15 at 100Kpcs.
