Please use within the maximum rating and under the recommended operating conditions.
In particular, please take care to avoid high voltage in the element.
The element could be destroyed if the rated range should be exceeded.
Please take measures to protect against surge voltage and static charges in storage, handling, and mounting in a circuit.
Use Hall effect ICs in a manner that does not allow element to make contact with the driving circuit.

Please do not apply excessive force between lead and package when carrying out lead forming.
And, please bend at least 2mm from package to avoid a force on between lead and package, if you bend the lead in the thick direction.

Although the reference conditions are shown as follows, please apply them only after careful examination and confirmation by the customer.

Please follow the procedure below when cleaning solder flux etc.

Please avoid direct sunlight when the products are stored, and keep them at normal room temperature and humidity as far as possible.
(Preferable storage condition is 5°C to 35°C and 40% to 85% RH.)

If the elements are stored for an extended time (two years or more) under the general storage conditions for semiconductors, the soldering characteristics of the lead terminal and the electrical characteristics could deteriorate; therefore, only use such elements after verifying their soldering and electrical characteristics, etc..
We recommend long-term storage in a nitrogen atmosphere.
The lead of the element will be oxidized by the oxygen in the atmosphere, and the soldering characteristics will deteriorate if the elements are stored in a normal atmosphere.

Please bear in mind the following labels when handling Hall Elements with Static Awareness Labels below, which alert handlers and users of the devices to the possibility of electrostatic damage.
1.	Level of Electrostatic Discharge...Ethanol and isopropyl alcohol
	Typical value of breakdown voltage is described below.   Machine model(*1) Human body model(*2) HW-series 200V < 2000V < HG-series 80V < 800V < HQ-series 50V < 200V < HZ-series 100V < 500V < (*1)EIAJ ED-4701(C=200pF,1time) (*2)EIAJ ED-4701(C=100pF,R=1.5kΩ,1times)
2.	The general cautions for Preventing Electrostatic Discharge
	(A)	Environment
		One factor which can lead to the generation of electrostatic discharge is the lack of humidity. Humidity should be controled at 40 to 75%RH in the work environment.
	(B)	Workplace
		Conductive floorings (sheetings and coatings) must be used to prevent electrostatic discharge .
	(C)	Operators
		Body-grounding articles such as wristband must be worn without fail when touching circuit boards or the devices. Also be absolutely sure to inspect periodically. The antistatic overalls and shoes may be worn.
	(D)	Equipment, instrument, and supplies
		The instruments and equipments that handling or touching the devices must be grounded.. When soldering iron is used,it must be grounded without fail. The ionizer may be used,when insulator may touch or approaches.
	(E)	The others
		When transporting the devices, use a container that will prevent them from becoming electrostatically charged by housing them , and avoid using the objects which easily become electrostatically charged.
