Frequently Asked Questions
Which battery chemistry and cell size does the SMTU2477N-LF.TR holder accept?
The SMTU2477N-LF.TR is designed to accept CR2477N lithium coin cells, which are 3 V nominal, 24.5 mm in diameter. This battery chemistry provides a stable 3 V output throughout most of its discharge cycle, making it suitable for real-time clock and memory backup applications requiring long shelf life.
How is the SMTU2477N-LF.TR packaged and what quantity comes per reel?
The SMTU2477N-LF.TR is supplied on tape-and-reel packaging with 250 pieces per reel, indicated by the .TR suffix. This format is compatible with standard surface-mount pick-and-place equipment, enabling efficient high-volume PCB assembly without manual component handling.
For which end-product applications is the SMTU2477N-LF.TR best suited?
The SMTU2477N-LF.TR is well-suited for real-time clock backup in embedded systems, industrial meters, and IoT edge devices that require a CR2477N 3 V coin cell for standby power. Applications such as GNSS receivers, medical monitoring equipment, and smart building controllers commonly use this holder type to maintain time-keeping and SRAM data during main power outages.
Is the SMTU2477N-LF.TR RoHS compliant and suitable for lead-free soldering processes?
Yes, the LF suffix in SMTU2477N-LF.TR indicates a lead-free construction, making it compatible with RoHS-compliant reflow soldering processes at standard SAC305 peak temperatures of approximately 260°C. This ensures the holder meets EU RoHS Directive requirements for hazardous substance restrictions in electronic equipment.
