Technology Research Corporation
5250 140th Avenue North
Clearwater, FL 33760

     We have represented Technology Research Corporation, a Florida corporation
(the "Company"), in connection with the preparation and filing with the
Securities and Exchange Commission (the "Commission") of a Registration
Statement on Form S-8 (the "Registration Statement"),  for registration under
the Securities Act of 1933, as amended (the "Securities Act"), of a maximum of
300,000 of the Company's common stock, par value $.51 per share (the "Common
Shares"), issued to or to be issued pursuant to the Technology Research
Corporation 2000 Long Term Incentive Plan (the "Plan").

Based upon our examination of such documents and other matters as we deem
relevant, it is our opinion that (i) the Common Shares to be offered by the
Company under the Plan pursuant to the Registration Statement have been duly
authorized and, (ii) when issued and sold by the Company in accordance with the
Plan and the stock options exercised thereunder, will be legally issued, fully
paid and nonassessable.

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.  In giving such consent, we do not admit hereby that we
come within the category of persons whose consent is required under Section 7
of the Securities Act or the Rules and Regulations of the Commission
thereunder.


Very truly yours,

/s/ Randy K. Sterns
