Advanced Crystal Technology says it has further reduced the size of surface mount crystals by introducing the ACT200. Measuring just 8,0 x 3,8 x 2,5mm, the new 32,768 kHz ACT200 is compatible with existing PCBs, yet occupies 50% less volume. Suitable for many personal, portable domestic and mobile applications, the ACT200 also requires very low drive level at 1 µW maximum.
Frequency tolerance to ±5ppm, and combined with low frequency temperature coefficient at -0,034ppm/°C, creates a stable reference throughout the industrial temperature range -40 to +85°C. Equivalent series resistance, ESR, is 50 kOhm, and typical load capacitance is 12,5 pF.
By retaining the footprint of previous generation 32,768 kHz watch crystals, the ACT200 is drop-in compatible with existing designs, while the reduced dimensions allow designers to save weight and space.
The ACT200 is suitable for automatic placement from tape and reel, and is able to withstand peak soldering temperature up to 260°C.
