Patent issued for method of collecting and transmitting data using existing wireless network

1 March 2000 Telecoms, Datacoms, Wireless, IoT

The first completely leadless resonators in the kHz range are smaller than the leaded versions and lighter, claims Murata, the manufacturer.

Designed for use in remote controllers and keyless entry systems, digital still cameras, tuner packs, car navigation systems and general surface mounting applications, they offer an 86% weight reduction and a 67% footprint reduction. Height is down by 33% to 2,0 mm maximum.

Until recently there was little real demand for smaller resonators and applications were predominantly in larger appliances. This lack of interest was compounded by the resonator's need for space within the package in which to vibrate.

Changing market demands have resulted in smaller, lighter packages such as the CSKCC-E series. Murata says a change from the conventiona area vibration mode that required space in the corners, to a lengthwise vibration demanding advanced technology for mounting the ceramic element, made the whole concept viable.

Key features include a true SMD footprint with no leads protruding. Dimensions of 6,5 x 3,1 x 2,0 mm, a weight of only 60 mg, a frequency range from 400 to 600 kHz, initial tolerance of ±0,5%, frequency shift over the temperature range -20 to 80°C of ±0,3% and resonant impedance of 300 y maximum.
