The Benefits of the MC405/406 32.768kHz
· The most cost-effective SMD 32.768kHz product in the market. · Industrial temperature range of -40°C +85°C is standard. · The excellent heat characteristics of Seiko Epson built-in tuning fork resonator make them suitable for all surface mount soldering techniques. · Automatic insertion is possible. The conventional mount mini-cylinder cannot be mounted by most equipment, meaning in general it is hand-soldered. The production cost saving of the MC405/406 is estimated at £0.10 per unit in volume. · Steps such as lead forming and cropping are not required. The devices are packaged in tapes already and can be loaded in the mounting equipment as is. · MC406 is second sourced by the ACT 90SMX package.
