Important note:

ASM GmbH is continually working to improve the quality and reliability of its products. MTBF (using MIL217) is well

above 10 years (in most cases even more than 100 years). Nevertheless, electronic devices in general can

malfunction or fail due to their inherent physical and chemical properties. It is the responsibility of the buyer, when

utilizing ASM GmbH products, to observe standards of safety and to avoid a situation in which a malfunction or

failure of a device could cause loss of human life, injuries or damage to properties.
