Reflow Compatible SMD Tuning Fork Crystal from AVX Combines High Reliability and Small Size

MYRTLE BEACH S.C. - AVX Corporation, a leading manufacturer of advanced passive components and interconnect solutions, has developed a highly reliable surface
mount crystal resonator that provides a nominal frequency of 32.768kHz in a small ceramic package of 3.2mm x1.5mm and a profile of only 0.8mm. Designated ST3215SB, the reflow compatible tuning fork crystal resonator has a frequency tolerance of +/-20ppm, a maximum ESR of 70kW and an operating temperature range of -40°C to +85°C.

Ideal for consumer and mobile equipment applications, the ST3215SB resonators are Pb free and RoHS-compliant. Standard capacitance ranges are 9pF to 12.5pF and low capacitance versions, 7pF or less, are available on request.

"Already one of the biggest suppliers of MHz crystal products, AVX/Kyocera merged with
a company called Hertz to add unique kHz design capabilities to its own expertise in high-reliability ceramic packaging and competitive price structuring," said Akira Honda, Product Marketing Manager at AVX. "These new devices offer equivalent performance to similar industry standard devices, but benefit from our ultra-reliable / cost competitive ceramic packaging technology."

Pricing for the ST3215SB surface mount crystal resonator is set at competitive market levels with a lead time of 14 weeks.
