The 91MLA1200303R air-core inductor is engineered to meet the performance requirements of the high-frequency RF sector, delivering superior electrical characteristics through its precision structural design.
Featuring 12-turn winding and a 0.03mm thin wire diameter, it balances inductance accuracy and high-frequency signal transmission stability. Its wide frequency coverage of 1.5-18GHz can satisfy the application needs of multi-band RF equipment. With a rated current capacity of 200mA and a broad operating temperature range from -55℃ to +125℃, it is suitable for complex and harsh working environments.
The product is compatible with soldering processes. During assembly, the length of leads at the transmission line end should be strictly controlled. After debugging, glue fixation is required, which can effectively avoid signal interference and ensure the reliability of feed choking. Under compliant storage conditions, the product can be stored stably for 1 year, providing strong support for mass production and long-term supply. It is ideal for manufacturing various high-end RF communication equipment.
