Solving issues of the real-time clock (RTC) module for industrial use
All-solid-state batteries operating in a wide temperature range can contribute as a backup power for RTCs under harsh conditions.
Maxell’s PSB401010H all-solid-state battery uses a ceramic package for the casing, which enables surface mounting∗1, and can be placed in a reflow furnace with other SMDs (surface-mounted devices), eliminating the need for a separate process for battery connection. In addition, a battery holder is not required on the board, so it saves space and reduces the manufacturing processes.
With its safety∗2 and temperature characteristics, PSB401010H has a wide discharge temperature range of −50 to 125 deg. C, covering the usable environmental temperature of RTCs, and can be applied as a backup power supply for RTCs under harsh temperature environments.
In addition, the long-life characteristic∗3 of PSB401010H eliminates the need to replace batteries every few years, as is the case with primary batteries, thereby reducing maintenance man-hours.
