PKR-PI from Ericsson

Offering users a pinned version of its MacroDens PKR DC/DC module, Ericsson Power Modules' PKR-PI is said to offer downgrade compatibility and full interoperability with the original through-hole version of Ericsson's MacroDens PKF module.

Featuring a failure rate of less than 100ppm, the PKR-PI is aimed at customers who do not require SMT modules and prefer conventional, through-hole assembly methods and the deployment of pinned modules. The modules are suited for existing MacroDens PKF-PI customers who wish to migrate to Ericsson Power Modules' latest DfE platform, the PKR-PI.

Due to different input voltages offered by the MacroDens PKR series, the product is suitable for various applications such as ICT, industry, transportation and process control.

PKR-PI is based on an optimized platform that lowers environmental impact, simplifies manufacturing process and reduces costs. By simplifying the mechanical design and assembly processes, and through the use of proprietary control circuits, PKR-PI is optimized for cost efficiency, said the company. The product is designed to avoid the use of unnecessary chemicals and processes. Moreover, its low weight reduces transportation costs and energy consumed during manufacturing.

The PKR-PI boasts a 7.2 million-hour predicted MTBF figure at 40C ambient temperature. With a low profile, the PKR-PI's height of less than 9mm enables it to be used in tight board-spacing apps.

A range of 22 ratings is available for industrial use through to 48V telecom applications and features a wide input range for combined 24/48V applications. As an extension of the PKR surface mount (SI) range, all ratings are now available in SI and PI formats.
