FEATURES
Monitor Products’ 970H/HHT and 980H/HHT series of half-
size clock oscillators combine state-of-the-art, thick film,
hybrid technology with precision manufacturing, resulting
in products of unsurpassed accuracy and reliability. Their
all-metal, resistance-welded cases ensure environmental
protection and shielding to minimize EMI/RFI.
