Our low-cost R-78K-2.0 series is now available with 90 degree, pre-formed, through-hole pins for horizontal mounting where a low profile of just 8.5mm is an advantage. The new version R-78K-2.0(L) has the same electrical specifications and fixed output options from 1.2V to 15V, with a maximum input voltage of 36V.

The low-profile, horizontal mounting option suits products with component height restrictions and is complemented by the high efficiency achieved, peaking at 96%. This means that no heatsinking is required, further saving space and costs. The R-78K-2.0(L) series has a maximum case temperature of +110°C, allowing operation to +90°C ambient for some variants without derating, dependent on the input voltage. Quiescent current is 1mA maximum for energy savings and extended battery life in portable equipment.

Input under-voltage and short-circuit protection is provided, and the parts are certified to IEC/EN 62368-1 3rd edition.
