What are the key features of SMTU1225-LF?
- Designed for CR1225 coin cell batteries (12.5mm diameter, 2.5mm height)
- SMD surface-mount footprint for automated PCB assembly
- Gold-plated contacts ensure low contact resistance and long-term corrosion resistance
- Lead-free (LF) construction for RoHS compliance
What is SMTU1225-LF used for?
The SMTU1225-LF is used in low-power IoT devices, real-time clock (RTC) backup circuits, and wearable electronics where a replaceable CR1225 3V lithium cell provides backup energy. Its surface-mount design integrates cleanly into high-density PCB layouts without through-hole drilling, reducing manufacturing steps. It is also commonly used in medical sensors, remote controls, and compact handheld devices that rely on coin cell power.

Frequently Asked Questions
Which battery size does the SMTU1225-LF accept and what voltage does it supply?
The SMTU1225-LF is designed to hold a CR1225 coin cell, which has a 12.5mm diameter and 2.5mm height, supplying a nominal 3V output. This voltage is suitable for powering RTC chips, low-power microcontrollers, and memory backup circuits directly.
How does the SMD footprint of the SMTU1225-LF compare to through-hole coin cell holders in terms of board space?
The SMTU1225-LF occupies only the CR1225 footprint on the top copper layer without requiring through-hole vias, saving approximately 1-2mm of vertical clearance and eliminating manual insertion steps. This enables fully automated assembly on double-sided PCBs with less than 5mm component height constraint.
Is the SMTU1225-LF suitable for use in an RTC backup application running at 3.3V logic?
Yes, the CR1225 cell in the SMTU1225-LF provides 3V nominal, which is within the operating range of most 3.3V RTC ICs. The holder's gold-plated contacts maintain low contact resistance below a few milliohms, ensuring stable current delivery during backup mode for months or years depending on RTC quiescent current, typically 1µA to 10µA.
What distinguishes the lead-free LF variant of the SMTU1225 from earlier non-LF versions?
The LF suffix confirms the SMTU1225-LF uses lead-free solder-compatible terminations, meeting RoHS Directive requirements. This makes it suitable for export to EU and other regulated markets, and compatible with standard SAC305 lead-free reflow profiles up to 260°C peak temperature.
