AEC-Q200 SMD Transponder Coil RFID2410 Series for Passive Keyless Entry Systems

The RFID2410 series SMD transponder coil is designed for 125kHz low-frequency RFID applications. It uses a high-sensitivity core material, offering excellent signal reception and strong anti-interference performance. The product is AEC-Q200 qualified for automotive use. It maintains stable electrical characteristics across a wide temperature range. It is also vibration-resistant and drop-resistant, meeting the strict reliability requirements of automotive and industrial environments. The square SMD package supports automated surface-mount assembly, reducing production costs. It is widely used in automotive TPMS, passive keyless entry, immobilizer anti-theft systems, low-frequency access control tags, and industrial asset tracking.

Q: What is the operating frequency of the RFID2410 series? Does it support other frequencies?

A: The standard operating frequency is 125kHz, which is the mainstream carrier frequency for low-frequency RFID. If you require 134.2kHz or other custom frequencies, please contact our sales team to confirm feasibility.

Q: Is this product AEC-Q200 qualified? What is the temperature range?

A: Yes. The RFID2410 series is AEC-Q200 qualified for automotive use. The operating temperature range is -40°C to +125°C. It is suitable for harsh temperature environments such as automotive engine compartments.

Q: How do I choose the right model based on sensitivity (S value) and Q factor?

A: A higher S value (sensitivity) means the coil induces a higher voltage in the same magnetic field, resulting in a longer read range. A higher Q factor means better frequency selectivity and stronger anti-interference capability. For long-distance reading, choose models with high S value. For high-noise environments, choose models with high Q factor.

Q: Does this coil support reflow soldering?

A: Yes. The RFID2410 series uses high-temperature resistant materials and an SMD package design. It is compatible with lead-free reflow soldering and suitable for automated SMT production lines. The recommended peak temperature is 245°C (not exceeding 260°C).
