Belvidere, Ill. NDK (Nihon Dempa Kogyo Co., Ltd.) offers two crystal resonator options to provide frequency control for transmitters or receivers in tire pressure monitor systems (TPMS).
The new NX5032SD crystal measures 5.0 x 3.2 mm with a height of 1.0 mm, while the larger NX8045GB device measures 8.0 x 4.5 mm with a height of 1.8 mm. Both crystals are hermetically sealed in ceramic surface-mount packages that exceed the tough shock, vibration, drop, and acceleration requirements for TPMS applications.
These crystals are said to deliver excellent stabilized startup characteristics over the wide operating temperature range of -40° to 125°C. The NX5032SD is available in the frequency range of 9.84 MHz to 40 MHz and the NX8045GB offers a frequency range of 5 MHz to 40 MHz with excellent frequency stability of ±50 ppm at 25°C.
The NX5032SD is designed to reduce electromagnetic interference (EMI), which is critical for in-hub applications, said the company. Both of these crystals are RoHS compliant and are designed to withstand the requirements of reflow soldering using lead-free solder. NDK is also TS 16949 certified.
The NX5032SD and NX8045GB devices (packaged on tape and reel) are priced at approximately $0.55 and $0.43 each, respectively, in quantities of 10,000. Delivery is 12 weeks.
