* Choose the element size while taking surge conditions into consideration.
■
Do not apply vibration, impact (drop impact, etc.), or pressure strong enough to crack the outer sheath resin or absorber
body of the surge absorber.
■
When coating the surge absorber with a resin or embedding it in a resin mold, avoid using a resin that degrades the
surge absorber.
■
Do not bend or apply a force to the lead of a D-type surge absorber close to the outer sheath resin.
